IPC: H04M1/31
Filed: 1964-05-29
Abstract: 1,030,914. Telephone dials. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 2, 1965 [May 29, 1964], No. 22251/64. Heading H4K. The impulsing contacts of a telephone dial mechanism are provided by magnetizable sealed reed contacter which are caused to open and close during the return motion of the dial from a selected digit position by two rotating permanent magnets as each passes in front of the reeds. Each rotating magnet nullifies the effect of a permanent magnet which otherwise holds the contacts closed. The usual lost motion period is provided by another magnet mounted on a disc rotated through the same angle as the dial so that during the last stage of the dial's return movement this magnet comes near enough to the reed contacts to hold them closed irrespective of the two rotating magnets. Two further sealed reed units form the off-normal contacts of the dial mechanism and are closed as a second magnet mounted on the above disc moves away at the beginning of dialling. The magnetic axes of the two magnets mounted on the disc are mutually perpendicular to avoid interference in the magnetic actions.

Title: Improvement in radio distance determining system
IPC: G01S13/34
Filed: 1945-08-29
Abstract: 646,361. Radiolocation; valve amplifying circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 29, 1945, No. 22307. Convention date, March 2, 1944. [Classes 40 (v) and 40 (vii)] In a frequency-modulated radio distancedetermining system the effects of extraneous signals and random reflections are minimized by controlling the frequency response of the beat-frequency channel in accordance with the amplitude and/or frequency of the beat frequency. In a conventional system, Fig. 1 (not shown), the amplifier in the receiver, which feeds the beat frequency to the limiter and frequencymeasuring apparatus, is provided with an automatic gain-controlling circuit so that at low signal levels, corresponding to long range, the gain increases substantially linearly with frequency up to the frequency f corresponding to maximum range and thereafter decreases sharply as shown in curve 21, Fig. 2. As the signal level increases the frequency response changes as indicated by curves 23, 25, 27, so that the effects of higher beat-frequencies produced by more distant objects are reduced. The gain-controlled amplifier comprises a valve 33, Fig. 3, with a circuit 43, 45, 47, 49 proportioned to give negative feedback at the lower frequencies which becomes a minimum, or slightly positive, at the upper frequency limit f, curve 81, Fig. 4. The amplifier output is fed through a circuit 51, 52 with the response indicated at 89 and a low-pass filter 53, 55, 57 with the response indicated at 91. The effects of these circuits combined with the gain characteristic 81 is to produce the overall gain characteristic 21, Fig. 2. To provide the gain control potential for valve 33, a diode 59 with a delay bias 65 is fed with the output from the amplifier and the smoothed rectified output is fed via a filter network 71, 73, 75 to the grid of valve 33. When the signal voltages rise to a sufficiently high level for the diode to operate, the negative bias fed to the amplifier grid has little effect over the negative-feedback range for frequencies from zero to f <SP>1</SP> but causes a rapid decrease in gain over the range f to f to produce the gain characteristics such as 83, 85, 87, which correspond to the overall gain characteristics 23, 25, 27. It is also stated that the gain-controlling voltage may be derived as a function of the frequency of the beat signal by obtaining it from a suitable frequency measuring circuit, which if connected prior to the limiter will provide a voltage dependent upon amplitude also. Specifications 317,068, [Class 40 (v)], and 594,766 are referred to.

Filed: 1963-06-05
Abstract: 1,031,199. Circuits employing bi-stable magnetic elements. MULLARD Ltd. June 4, 1964 [June 5, 1963], No. 22347/63. Heading H3B. The terminal rung of a laddie core 1 is split into two equal parts 12, 13 and an output winding 5 wound around one of the parts is connected to or forms a winding on a second laddie core 7. If a binary " 0 " is stored in all the parts of the laddie 1 the flux distribution is as shown in Fig. 2 so that during a drive period when a drive pulse is applied to drive winding 3 to write a " 1 " into a core there is a flux reversal in part 13 and a complete flux path round the whole of the laddie is achieved as shown by dotted arrows, Fig. 3, resulting in an output current being induced in winding 5. After the end of the drive period a prime and a set pulse are applied over windings 6 and 2 respectively to cause a distribution of flux as shown in Fig. 4. The set pulse does not result in an output pulse since the flux circulates around the rung prior to the terminal ring. The output winding 5 forms a hold winding on core 7 and an auxiliary core 10 provided with a prime winding 11 prevents changes in flux in laddie core 7 being transferred back to core 1. More than one output winding 5 may be employed to interconnect a plurality of laddies. Alternatively, the single output winding may be connected in series with a plurality of hold or input windings.

IPC: F23C7/00
Filed: 1958-07-14
Abstract: 873,524. Supplying air to burners. BABCOCK. & WILCOX Ltd. July 14, 1959 [July 14, 1958], No. 22538/58. Class 75(1). An air register comprises two sets of pivoted blades 7, 8 arranged alternately, the blades 7 of one set being pivotable in an anticlockwise direction from their closed positions and the blades 8 of the other set being pivotable in a clockwise direction from their closed positions whereby the register can be set to cause the air to be given either a clockwise or an anticlockwise rotation. Each set of blades is separately actuated by a ring 20 and 21 rotatably mounted on the front plate 1 of the register. Each blade 7 is welded to a sleeve 14 secured by screws 15 to a shaft 9 extending between the front plate 1 and the rear plate 2 of the register. Each blade 8 is welded to a sleeve 13 rotatably mounted on the shaft 9 and extending through the front plate 1 of the register. The coupling between each of the shafts 9 and the operating ring 20 for the set of blades 7 comprises two relatively movable arms 27, 28. Arm 28 is clamped by a bolt to the shaft 9 and arm 27 has a hole in which the shaft 9 fits loosely. A spring 34 is interposed between the outer ends of the arms 27, 28 and causes the other ends of the arms to grip tightly rollers 36, 37 mounted on a pin 29 projecting from the ring 20. The ring 20 is rotated by a shaft 70, a crank 74 and a link 71. When the blades 7 reach the closed position their free edges abut bars 6 extending between the front and back plates 1, 2 but further movement of the operating ring 20 is possible and causes displacement of the arms 28 relative to the arms 27 and compression of the springs 34. In this position the link 71 between the crank 74 and the ring 20 is in a slightly over-centre position. The sleeves 13, to which the other blades 8 are connected, are coupled in a similar way to the operating ring 21. The front plate 1 has an aperture 4 for a burner and the rear plate has a frusto-conical throat 3. In a modification Figs. 4, 5 (not shown) the blades are flat and are secured by springs and bolts to arms extending from rotatable sleeves coupled by forked brackets to an operating ring. In the closed positions of the blades the springs between the blades and the arms are compressed.

Title: Improvements in or relating to machines for sorting perforated cards
IPC: G06F7/06
Filed: 1930-07-26
Abstract: 359,073. Statistical machines. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. July 26, 1930, No. 22594. Convention date, July 27, 1929. [Class 106 (i).] Sorting cards.-In a machine for sorting perforated record cards, the latter are conveyed between guiding means, leading to the sorting boxes, which consist of flexible members, such as wires, threads, bands, or cat-gut strings, which are normally arranged in one and the same plane along the path of the cards. The construction illustrated is for code cards, the four hole positions in each column having the values 1, 2, 4, and 8. The cards 1 are fed by picker mechanism 5, 6 from a magazine 2 to the reading station, where they are held by members raised by levers 14, 15 and cams 17, 18. The card column being read is sensed by four card feelers 27, and each feeler sensing a hole closes its contacts 20, 21, Fig. 3, to energize the corresponding one of four magnets 31, Fig. 4. Each magnet energized shifts its corresponding one of four code wheels 32, which is notched internally, so that when a pawl 35 on shaft 33 subsequently rotates, it moves until it reaches a line of four aligned notches in the four wheels 32. This gives a differential movement, according to the value in the card column, to shaft 33 which carries a cam 36, Fig. 5, which is felt by a pin 37. The guiding wires 51 in one and the same plane are soldered at their right-hand ends to the partitions 50 of a funnel 40. When the pin 37 is lowered to feel the cam 36 it controls the vertical swinging of the funnel 40 so that the correct channel therein is presented to receive the card and convey it to the wires 51. The card-reading device, Fig. 3, is adjustable along the line of travel of the card by gear wheels 58, Fig. 5a, racks 59 and knob 60, the position being indicated by scale 64 and indicator 66. The reading device is also adjustable transversely to read any particular card column by spindle 61 and knob 62, an indicator 65 reading against a scale 63.
